Global Lake and Reservoir Storage Estimates from Satellite Data

Satellite-derived storage time series provide surface water estimates for several hundred lakes and reservoirs worldwide. The dataset spans a potential 25-year period from late 1992 to 2017, supporting long-term trend analysis and global water dynamics models. It serves as a precursor to the SWOT mission, offering hydrological measurements with typical satellite data quality flagging.

Use Cases

• Analyzing long-term trends in lake and reservoir storage based on a 25-year time series.
• Modeling human impact on the global water cycle using surface water storage estimates.
• Assessing water dynamics for resource management across several hundred global sites.
• Preparing for SWOT mission data formats and variables using pre-SWOT hydrological measurements.

Strengths

• Provides estimates for several hundred lakes and reservoirs globally.
• Time series potentially spans a 25-year period from late 1992 to 2017.
• Designed with a quality level suitable for long-term trend analysis.

Limitations

• Column names and exact row counts are unknown across all sources.
• Sources disagree on the last updated date (2019 vs. 2026).
• The license is specified as 'other-license-specified' without details.
